Questão jurídica principal
Whether the judge who ruled on admissibility of the opposition may later hear the action on non-return to better fortune
Decisão extraída
No. The prior participation created an objective appearance of bias because the later action functionally reviews the same issue in a contradictory procedure.
Fundamentação extraída
Both proceedings concern the same enforcement matter and largely the same evidence; the second stage is a functional reconsideration of the first, so the outcome no longer appears open and the judge cannot review his own prior decision.
